Mr Livingstone became the focus of hundreds of memes after he refused to back down over his comments.

A counter was even started, recording the number of days since he had last mentioned the Nazis.

Right now, it’s set at zero.

The row started while he was defending Labour MP Naz Shah, who had shared a meme suggesting Israel could be moved to America.

‘When Hitler won his election in 1932, his policy then was that Jews should be moved to Israel. He was supporting Zionism before he went mad and ended up killing six million Jews,’ Mr Livingstone said.
